There's a bug in the current stable Nautilus release that causes a loop and/or
crash in get_obj_data::flush (you should be able to see it gobbling up CPU in
perf top). This is the related issue: https://tracker.ceph.com/issues/39660
<https://tracker.ceph.com/issues/39660> -- it should be fixed as soon as 14.2.5
is released (any day now, supposedly).
Hope this helps,
